Ugh, it's not as easy as I thought but...

```d
   import std.utf;
   // option 1 (if you want a range that's usable elsewhere)
   str.map!(c => uint(c).toChars!(16, char, LetterCase.upper))
       .joiner("-".byCodeUnit) // byCodeUnit needed because of autodecoding
       .writeln;

   // option 2 (if the point is just to print)
   writefln("%-(%02X-%)", str);
```
